No screen non-stop net changer (without wire mesh filter) using super wear resistant alloy steel mesh filter, filters are with high precision laser processing equipment produced by anti clogging one-way melt filtration pores, have allowed by melt, blocking effect of impurity filtration system equipped with other synchronous operation of rotor blade in removing impurity, melt plastic thin hole through, impurities and dirt in filter plate on one side,In the rotor blade to remove impurities, 3 RPM speed the process, the part of impurities was pushed to save miscellaneous chamber, so as to achieve the purpose of continuous reciprocating filtering, to save miscellaneous chamber after impurities accumulated to a certain number, operator manually complicated institutions get rid of the impurities, so the cycle, 24-hour self-discharging, without the function of the filter Screen changer without mesh adopt super wear-resistant and alloy steel mesh filter.The filter is made of high precision laser processing equipment to prevent clogging of unidirectional melt filter micro holes, which allows the molten plastics to separate impurities.
